A steady red light indicates the printer may be out of paper or the cover is open. Check that the printer still has paper and close the cover. If the steady red light persists:
- Install genuine label paper. Do not remove the green sticker from the core of the roll.
- Pull out the first label so it protrudes from the printer.
- Close the paper tray cover.
Check the status of the light. It should be a steady green (or blue if connected via Bluetooth).
If the steady red light persists and the printer is or has been connected via the app, click on “Unconnected” in the upper right corner of the app to confirm the specific error, otherwise contact customer service for further assistance.
